Richard Engel's 'Hidden Planet' premiere: Discovering Timbuktu

In the first installment of Rock Center's Hidden Planet series, NBC News Chief Foreign Correspondent Richard Engel travels to Mali, on the edge of the Sahara desert, to discover the city of Timbuktu.

In an unexpected departure from his usual beat of war-torn territories and areas of conflict, each month Engel’s Hidden Planet will set off on journeys of discovery to find the most awe-inspiring, rarely seen locations around the globe. From the Lost City of Timbuktu to the tunnels beneath the Giza Pyramids, and everywhere in-between, this is a side of Engel - and the world - that viewers have never seen before.
